ABSTRACT
The purpose of this project is to design and construct a new version of tunnel
inspection robot equipped with new application such as a gas sensor and water detector.
This new robot is developed on a new platform that is more functional so that the robot
can work under various condition and surfaces.
The tunnel inspection robot is made up of a moving platform controlled by two
DC motors. On top of the moving platform is a turntable controlled by a stepper motor
via wireless system made up of a transmitter and receiver. On top of the turntable is a
miniature camera connected remotely to a computer system for monitoring and manual
steering of the robot. Together with the camera is search light for lighting up dark areas.
The robot is also equipped with a gas sensor to detect methane gas and inform
the operator of poisonous gasses in the environment. A water detector device is also
attached to ensure that the robot can avoid water logged places to prevent flooding of the
robot. The new robot is also equipped with an obstruction detector to enable the robot to
move automatically unobstructed. The new robot is more rugged so that it can reach
dangerous and difficult areas.
Apart from that, the tunnel inspection robot has been integrated with software to
provide security for accessing the robot. This is to avoid abuse or wrong utilization of
